OYAH INGREDIENT LIBRARY

Probiotics

Probiotic effects are strain- and condition-specific. A species name and total CFU count do not show that a product matches a clinical trial.

What they are

Probiotics are live microorganisms intended to provide a benefit when administered in adequate amounts. A full identity includes genus, species and strain, such as a letter-number strain code. Different strains within the same species can behave differently.

What human research suggests

Some strains or combinations have evidence for defined digestive outcomes, but evidence varies widely by condition and population. A label stating “20 billion CFU” describes a viable count under stated conditions; it does not identify the studied strain or prove a clinical effect. Count at manufacture and count through expiry are also different claims.

SAFETY & CONTEXT

What to consider before use.

Probiotics are generally well tolerated by healthy adults, with temporary gas or bloating possible. Rare serious infections have been reported in people who are severely ill or immunocompromised. Those with central lines, major immune suppression, critical illness or significant underlying disease should seek clinical guidance before use. Follow the product’s storage directions.
